International Academy of Astronautics 1.2. Feedback from Beijing 2013 Statistics: -Based on available information, 3 rd most attended Symposia after C1 (Astrodynamics) and A3 (Space Exploration) - Good work of the Chairs and Rapporteurs, with only 5% No-Show: best score of the Congress according to available information - 16 papers proposed for publication in Acta Astronautica - Note: it should have been a “low year” due to the 6 th Darmstadt conference

International Academy of Astronautics A6: Space Debris Symposium Liou – Bonnal The Symposium will address the complete spectrum of technical issues of space debris: measurements, modelling, risk assessment in space and on the ground, reentry, hypervelocity impacts and protection, mitigation and standards, and Space Surveillance. A6.1: Measurements: Schildknecht – Agapov – Carroll This session will address advanced ground and space-based measurement techniques, relating processing methods, and results of space debris characterization. A6.2: Modelling and Risk Analysis: Anselmo – Liou – Hanada This session will address the characterization of the current and future debris population and methods for in- orbit and on-ground risk assessments. The in-orbit analysis will cover collision risk estimates based on statistical population models and deterministic catalogues, and active avoidance. A6.3: Hypervelocity Impacts and Protection: Francesconi – Sen Liu – Schäfer The session will address passive protection, shielding and damage predictions. Shielding aspects will be supported by experimental and computational results of HVI tests. Use of HVI techniques for debris mitigation. A6.4: Mitigation and Standards: Cazaux – Klinkrad – Yakovlev or Molotov This session will focus on the definition and implementation of debris prevention and reduction measures and vehicle passive protection. The session will also address space debris mitigation guidelines and standards that exist already or are in preparation at the national or international level. 1.3. Toronto 2014 A6 Symposium

International Academy of Astronautics Recall of a few basic rules  No paper, no show:  check that the paper is effectively loaded before the session  No show, no paper:  If the author doesn't present, the paper will be removed from proceedings  Status of the presenters:  Are we sure the authors will show up ?  Do we have their short bios ?  Try to contact them and ask to come 15’ in advance to check that everything is OK, Powerpoint, Videos…  Timing may be critical !  Please, do not overpass the standard 3 hours, except if there is nothing after  Have clear rules explained to speakers in advance  Keep time for Q&A  Publications: no dedicated IAC issue of Acta Astronautica any more  Selection of 2 or 3 best papers, if any !  Chairs and Rapporteurs may be asked to act as Peer Reviewers 1.3. Toronto 2014 A6 Symposium

International Academy of Astronautics Report on IAA contribution to IAC The goal is to deliver a global IAA report on results from the IAC, to be released outside through the web, a newsletter, or any other media to be discussed An e-mail has been sent to the Symposium Coordinators, asking for their inputs, and recommending to use the following process : -Ask session co-chairs and rapporteurs to write one or two pages on the scientific and technical content of their sessions (only the main findings) and to send it to the Coordinators either during the congress or just after (November 3) -Symposium Coordinators shall gather these inputs, check that there is no problem with them, and add some additional comments on the overall Symposium if any -Send the resulting package to the Academy IAC Technical Coordinator (November 21) -If these contributions are sent in due time, the global IAC Summary report shall be ready for SAC for approval on December 8 This report will be a high added value for the Symposium Coordinators in terms of visibility, for the Academy members and other people visiting our website in terms of awareness of what has been done during the IAC, and for the Academy in terms of recognition of its role in the operations of the IAC 1.3. Toronto 2014 A6 Symposium

International Academy of Astronautics Proposal for a Plenary Event or a Highlight Lecture We should organize ourselves to be capable of proposing a Plenary Event or a Highlight Lecture in Jerusalem -It requires a good preparation -Thematics, title, organization (Who? Moderator? Round table?...) -Proposal to be made before March meeting  Ideas are due within a couple of monthes Should we try a joint session? -With Satellite users B1, B2, … or Space Transportation D2 relative on end of life operations? -With Small Satellite B4, mainly on very small satellites operations?  May be complex as we need to have 9 good papers, or 6 + a good round-table…  Decided not to during the meeting 1.4.
